I had Intermountain Glass replace the front windshield in my Explorer. Called them on Thursday, had an appointment next morning, and got my car back.

These guys were awesome! I needed to get the springs in my window replaced, they took the time to teach me (twice) how to do it myself. They sold me.

I recently used Intermountain to replace glass in two small failed windows, recalling that six years ago they had done some highly satisfactory work.
